Expand selection to custom line - sublimetext2

Question

I am wondering if there is a out of the box way, or a plugin that can achieve the following behaviour in SublimeText3.
I would like to put the caret at a certain line. And then select all the text until another line number. The amount of lines should be variable.
For example put the caret on 10 and then expand selection to line 21 or line 104.
I hate having to hold down key or use the mouse for this action.

I wrote a simple plugin that allows you to enter a line to select until via an input_panel:
Features:
works bidirectionally
respects the current selection
only executes if there is a single selection

Code:
import sublime, sublime_plugin
class SelectToLineCommand( sublime_plugin.TextCommand ):
def run( self, edit ):
window = self.view.window()
selections = self.view.sel()
if len( selections ) != 1:
return
self.currentSelection = selections[0]
if self.currentSelection.a > self.currentSelection.b:
self.currentSelection = sublime.Region( self.currentSelection.b, self.currentSelection.a )
window.show_input_panel( "Select To Line Number", "", self.get_LineNumber, None, None )
def get_LineNumber( self, userInput ):
lineToRow_Offset = 1
row = int( userInput ) - lineToRow_Offset
selectionEnd_Row = self.view.text_point( row, 0 )
currentSelection = self.currentSelection
if selectionEnd_Row >= currentSelection.b:
selectionStart = currentSelection.a
selectionEnd = self.view.line( selectionEnd_Row ).b
elif selectionEnd_Row < currentSelection.a:
selectionStart = currentSelection.b
selectionEnd = self.view.line( selectionEnd_Row ).a
newSelection = sublime.Region( selectionStart, selectionEnd )
self.view.selection.clear()
self.view.selection.add( newSelection )
