Enable Back in RDM $HOST$ as variable to Advance Multivault Search

Hello,
I'm running on version 2026.1.24 in RDM, and I'm not able to add the variable of "Advance Search -> Multivault -> by $HOST$.
On previous version that was available and very useful if you don't have the IP on the name structure of the entry, or similar.
Now if i have all my entries with IP in $HOST$ i can not search it.
I open a chat with support and they confirmed that is not present on the next extended or the latest.
Please let me know
Thanks in advance
Nicolas
