How to keep the old UM V3 ?

Hi,
Is it possible to keep the old User Manager V3, because i find it much faster and easier to use, also it fits much better our needs.

At the time I am still using RouterOS v4.17, because if i Upgrade, my current UM will be replaced with the new one.

Is there an option to update to the latest RouterOS, but still keep the old UM interface (v3).

Thank for your help

P.s.
The reason why i want to keep the old UM is that i can handle each user-client separately, in the new version i always have to create a profile first, and then it will apply to all users…
Because we have only small hotspots at our Internet cafe, we are mostly making individual deals with clients, that meet their needs, and in that case i need to have the option to handle each client separately, and its very annoying if for each new client i have to make a separate profile…
