Is a batch operation to save a set of navigation properties possible? - json

Question

For example: Company has Employees.
By posting to odata.svc/Company(1)/Employees/$ref, I can save Company-Employee relation. Can I save multiple Company-Employee links this way using odata.svc/Company(1)/Employees/$ref/$batch ?
I tried but didnt work. If this is incorrect way, is there any other alternative ?

OData does support batching, I'm not sure what version of OData you are using but here is some documentation from v3 (v4 is the same) http://www.odata.org/documentation/odata-version-3-0/batch-processing/
In your example batch URL, you are adding $batch to the end of the URL that you are using, instead you have to POST to odata.svc/$batch with a request that contains details of all of the operations that you want to perform. For example, here is one of the request taken from that link:
POST /service/$batch HTTP/1.1 Host: host Content-Type:
multipart/mixed; boundary=batch_36522ad7-fc75-4b56-8c71-56071383e77b
