Vendor-class-id matching using wildcards or regex?

Hello all,
first thanks to Mikrotik for implementing vendor-class-id matching in v6.45. After implementing everything works as described as in wiki. However in linux isc dhcp I was used to match using first N characters of the vendor-id while some of the devices use for example firmware version as a part of the string delivered to the DHCP server. Currently I have to define multiple entries in the matcher, one for each FW version. Is there any way to use wildcards or any other way to match for example every vid beginning with “cisco-” ?

Thank you and kind Regards
Jakub

Hm, that could be very helpful for me too! I tried some variations of regex with no success. Any ideas?
