Setting up different fees for sub packages in a super package

I am having a problem setting up fee rules so they apply correctly across the two venues in our Live at the WSO super package.

What I would like is to set up fees that would apply to the package but different fees for the different venues since they go to different GLs. The 23/24 Venue Fee MCCH should apply to each of the concerts in the sub package at the Centennial Concert Hall. The 23/24 Venue Fee Burt Sub should apply to each of the concerts in the sub package at the Burton Cummings Theatre. The options I see in the fee rules, however, only let me select the whole super package under the Package option.

I feel like this can't be a unique scenario but I can't figure out how to make it work.
