One trial for multiple packages

I think it would be a nice new feature to have where store owners could make it so a trial can be given for one of multiple packages, instead of just for one package.

On my store, I have three subscription packages: Rainbow, Lightning and Fire. The more is being paid, the more perks the player has access to. In my situation, I would like it to be so they choose one of the three packages and get a trial, but then after that trial ends, they can not get the trial of the other two packages anymore.

If the trial is seperate for each package, players could use the free trial of each package to have access to similar perks for three times the period I would like them to. Therefore, I think this would be a great feature to have.
