Nesting room lists in m365 exhange online

Question

I saw that during the creation of equipment & room resource emails for calendars, you can make a version of a distro list specific to this purpose. At least I saw it for server 2019, not exchange online:
https://learn.microsoft.com/en-us/exchange/recipients/room-mailboxes?view=exchserver-2019#create-a-room-list

This will allow for a list to be selected when searching for rooms to reserve. This would help with grouping conference rooms by building, in the room finder in outlook.

Building 1 list
-Room A
-Room B
Building 2 list
-Room A
-Room B

What I need to know is if a resource list can be nested. So this is an example.

Region 1 list
-Building 1 list
--Room A
--Room B
-Building 2 list
--Room A
--Room B
Region 2 list
-Building 1 list
--Room A
--Room B
-Building 2 list
--Room A
--Room B

We just moved to M365, and have yet to recreate our room reservation emails. We just have so many buildings and conference rooms across the globe, we need more filtering options native to room finder in M365 exchange online.

Hi @Hartung, S

To my knowledge it may not be possible to use nested roomlist.

Would it be possible to set the roomlist's name to be like:
Region 1 - Building 1
Region 2 - Building 2

You may also need to configure the values (cities,buildings,floors) for the rooms and then add them to the corresponding roomlist.
