Accessing word counts in CAT payable through macro

I have asked XTRF support already, but I'm also trying my luck here.

Does anyone know how to access the word counts in CAT payables for the specific CAT tools through a macro? I know how to do this for the 'Other' CAT grid and had a very useful macro running that changed specific word counts, but with the switch to the specific Memsource grid this doesn't work anymore and I can't figure out how to access and change the word counts in this new format.

I have a bunch of unhappy project managers that suddenly need to do a lot more manual work, so for me it's pretty much every minute counts...

Anyone have experience with this, perhaps with the other specific grids for MemoQ or Trados?

Thanks!
