That shouldn't be a problem, it will probably follow the same logic as 
the A records. There will be a bit of a delay though, I am rebuilding my 
domain after it fell over big style.

BIG NOTE: Do not use the Debian 4.16 Samba packages on Raspberry pi OS 
32bit, it just leads to segfaults, the new 64bit Raspberry pi OS is okay.
