Feature request: selective netmask assign via DHCP

Hi

Using linux few months ago (before mt) I was able to assign netmask 32 to most of my hotspot clients, BUT if someone was using router or linux - I was able to assign selectively another (classic) netmask, while 32 caused client not working. I cannot find any solution for this in Mikrotik… It would be simply and nice in many cases…

regards!
