FinancialForce FFA Support while using PSA

in Ideas
Expensify should support the FinancialForce FFA connector as an option even if the FinancialForce instance is also running PSA.
We use PSA for timekeeping, but nothing else. I would love to get back to using Expensify and have it integrate with FinancialForce, but the dimensional tracking is not available through PSA - we have to use FFA. Unfortunately (and confusingly), Expensify will only connect to PSA if you have PSA installed. The FFA connector will install, but won't work (wasted a number of hours on that issue).
You should be able to configure and use the Expensify to FFA connector even if you are also using PSA in FinancialForce.
