Adding Create Subasset to the Right Click Token Dropdown

[davestaxcp]

If a user is looking to mint a subasset for a specific token they have token ownership for the process feel a bit to "manual" instead of an easy automatic process that the program is showing you how a subasset works:

Can we add "Create Token Subasset of TOKENNAME" to this list? ^

And when it shows this page for token subasset:

Subasset is automatically picked as well as this part is AUTO filled so it forces the user to do BIGGIEPEPE dot [insert subasset name here]

Basically just this would be "locked" so the user is just focusing on the subasset name:

It would be much less confusing to a new user.

Just my two sats <3
