Rezoning Fixed Seat Packages

We are currently selling fixed seat packages for next season, we only started doing this in our 18-19 season, so we only had about 2 years under our belt before the pandemic and we're still learning little nuances about the proper way to sell and update these performances. We had need to rezone some seats in order to add more inventory into a certain price zone, which we did for each package performance through season maintenance. However, the composite seat map and the best seat function are still recognizing those seats at their original price zone, so the ticket sellers aren't seeing the right zone markings in Tessitura, and TNEW flat out wont seat anyone in these rezoned seats. From what I've been told so far, they think the only way the composite map gets updated is by changing the zone map itself in facility manager. We do not wish to do that because not only do all the different packages use the same map, we have a large number of other performances in the same season that also use that same map. We're trying to work on a solution to fix the issue right now, but are trying to figure out the important take-aways from this experience so we know better for next year. 

So I wanted to get others thought on how you handle fixed seat package sales, especially if you do a lot of rezoning. We sell all our packages as immediately seated right away. We do not utilize any of the built in lineitem upgrade features from the order screen. We basically just tell people to call back later in the spring to see if any existing subscribers did not renew.

Do you setup each individual package with its own distinct zone map so you can rezone at the facility level at will? Do you restore the zones back to their original state when you setup rollovers, so even if they bought tickets at Price zone X this year, their rollover might be at Price Zone Y for the next season? Or do you leave the changes from year to year?

Any other pieces of advice, like "it took us years to figure out blank", or other fancy things you've learned would be very welcome. This is our 4th year of selling packages and it just seems like we often make things more complicated than they need to be.
