add a type

hi list,

i was trying to add a new type to snipsnap. is there an easy way i
missed in the how-to? or do i have do put my hands on the code - and in
this case where is the point to start?

i would like to add a type like person, or process to several snips -
that means choosing from the add label -> TypeLabel list.

i tried some constructs with adding snips named: Type:NewType but
without sucess.

thanks in advance,
gregor
