Different subsidiaries, same tax nexus, different tax group requirements Canada PST/GST

Hi

We have four subsidiaries, one nexuses to Canadian province 'British Columbia'. All subsidiaries have the British Columbia nexus attached to them.

The problem is that

Subsidiary A: Files Provincial Sales tax but not general sales tax.

Subsidiary B, C, D: Files Provincial Sales tax and general sales tax.

All following the law. But two different requirements.

Product items are not mutually exclusive to subsidiaries.

The tax lookup finds a tax item group that satisfies subsidiary B, C and D but not Subsidiary A. We have multi-subsidiary customer enabled.

Only solution I can think of is that for sales from subsidiary A, the sale is manually changed to the tax group that satisfies its requirements because there does not appear to be any functionality (i.e. separate tax nexux, or default tax codes) that will solve it.
