Amounts Menu (Spawner GUI) to check if player has enough inventory space

[Swoochy]

Hey. So when i withdraw an amounts of spawners some of the drop onto the floor, which is extremely annoying for everyone, im wonnderig if its possible to make the plugin check if the player has the free space, if a player has 1 slt available it would withdraw 64. 5 slots, withdraws 320 spawners etc. so it prevents the player from losing them.
