Bring back use of numbered dimension IDs

In Mcreator, you are able to get the numerical ID of the dimension the entity/player is in. But, there's no way to send them to that specific ID at a later point using procedures, because Mcreator quite ridiculously limits the "Switch dimension of" block to a dropdown menu which only shows vanilla dimensions and custom dimensions part of your mod. 
This makes it impossible to create portals compatible with other mods. 
Wasn't being able to switch dimension to a specific ID a previous feature? Why was it removed?? This helps no one.

Bring it back.
