Multiple Gates per Habitiat

I had a great idea to keep Staff in the back of habitats and guests in the front, in order to do this I wanted to puts gates on each side of habitats so keepers could go through them if necessary. I was upset to find that this is not an option. You can only have one habitat gate per habitat. Would it be possible to change this?

TLDR: Having multiple gates would help keepers pass through habitats without having to go around
