Add charges to 3PL bill

I see that the docs cover the below topics for 3PL billing:
Create a Bill
Recalculate a Bill
Update a Bill’s status
Submit a Bill to your client
Delete a Bill

But is there a way to add/remove charges (eg adhoc) to a bill using API?
Thank you

Hello @Raj!

Just as we discussed, that granularity is still not available in the API.

Kind regards,
