Making timed Minions stay while entering maps

With all the QoL additions lately, I suggest to make us able to keep timed minions (like animate-weapons) that we summon in our hideout, when entering a map

It has been a pet peeve of mine for a long time, espeically with the maven fight where we don't have a save space to pre-summon when we needed one of our 6 portals (unlike for example the sirius or elder fight, where we can enter and then have a save room to prepare our buffs before re-entering the fray)
