Is there any way to include dynamic info in the DHCP REQUEST?

Thanks, those would be great and in principal this is what I need.

However, what I am looking for is to set the option 125 ("vivso") in this
way. (I am aware that vivso is also something that can be requested from
the dhcp server, but I am working with the part that sends vivso *from* the
client *to* the server, as required in the TR111 spec.)
