Resetting and not resetting steps until next random encounter

Hello, I do have a very special case here.

In my game happens amost of the play time on the world map. There are several moments where you can rest at the map. The rest for itself doesn't teleport you to another map, so as such the remaining steps for a new random encounter are the same. That can be very annoying. So I need some possibility to reset the remaining steps without teleporting the hero to another map.

But I need also a solution for the opposite case. There is an item which you can use everywhere on the world map, it teleports you to another room and saves your location. After leaving the room you start where you left off, but yeah the remaing steps for the next encounter are resetted because of the teleport. That means players can use this "trick" as a cheat to avoid random encounters on the world map constantly.
So I need a method to save the remaining steps for the previous map.

Is there any option for the maker or some kind of plug-in. At least does someone know where the informations for random encounter rate lies and how I can manipulate it?

Hope someone knows a good trick. :/

remove the instruction to reset steps when teleporting to the alternate room maybe?
disable random encounters in that room if that'd disable the reset as well?
set the encounters to be region-based only on the main map?

Well, I need to find that instruction first. But even then I cannot just disable it, because it's important in some cases, the alternate room does not have any random encounter only the world map when you teleport back. The encounters for themselves are already region based.
I need to disable the encounter reset step temporarily only for just two teleports. (when you teleport into the alternate room and when you get back) everything else can stay the same.

Does someone has any other ideas?
