the find familiar spell grants the caster the ability to recast the spell to change the creature formed. its not a one cast and thats it. the tab should maybe have an option to create multiple Familiars to be saved to allow players the ability to create a few creatures they may want to swap in and out. there is a way to edit the existing but that may be time consuming especially in a fight. also for 1 AP the PC can pocket the familiar into a pocket dimension and then re-summon same creature for just 1 AP. i do not see that as a to do that either as an action when
Thanks for the request. I’ll pass it along!
