Upgrading a script - google-apps-script

Question

So i have this script
function onEdit(e) {
var editRange = e.range;
var rb1 = SpreadsheetApp.getActiveSpreadsheet().getRangeByName("RadioButton1");
// return if out of range
if (editRange.getSheet().getSheetName() != rb1.getSheet().getSheetName()) return;
var radioRange = { // RadioButton1 range
top : rb1.getRow(),
bottom : rb1.getLastRow(),
left : rb1.getColumn(),
right : rb1.getLastColumn()
};
var thisRow = editRange.getRow();
if (thisRow < radioRange.top || thisRow > radioRange.bottom) return;
var thisCol = editRange.getColumn();
if (thisCol < radioRange.left || thisCol > radioRange.right) return;
// make RadioButton1 named range behave like radio button
var numRows = rb1.getNumRows();
var numCols = rb1.getNumColumns();
var writeValues = []
for (var i = 1; i <= numRows; i++) {
var row = []
for (var j = 1; j <= numCols; j++) {
var currentRange = rb1.getCell(i,j);
var radioValue;
if ( currentRange.getA1Notation() == editRange.getA1Notation() ) {
radioValue = true;
} else {
radioValue = false;
}
row.push(radioValue)
}
writeValues.push(row)
}
rb1.setValues(writeValues)
}
from Switch based on checkbox tied between two cells in Google Sheets
so sorry i for got i have put the checkboxes into separate ranges
What ranges i Have
how do i make this now work for multiple ranges please?
also if there is a way to set the cells the check boxes are in rather than using a range to determine the checkbox pairs so i can move them around the sheet and tell the script where to look that would be better
My Google Doc

Description
The following example script shows how to toggle checkboxes like radio button in which only one checkbox of two remains checked. The checkboxes are grouped by rows as shown.
Code.gs
function onEdit(e) {
let rButton = SpreadsheetApp.getActiveSpreadsheet().getRangeByName("RadioButtons"); // A1:B5
let rCheck = null;
if( e.range.getSheet().getName() === rButton.getSheet().getName() ) {
if( e.range.getRow() < rButton.getRow() || e.range.getRow() > rButton.getLastRow() ) return;
if( e.range.getColumn() < rButton.getColumn() || e.range.getColumn() > rButton.getLastColumn() ) return;
// unchecked does not become checked, only check becomes unchecked
let offset = e.range.getColumn() === 1 ? 1 : -1;
e.range.offset(0,offset,1,1).uncheck();
}
}

Range.offset()
Range.uncheck()
