NPC token with rollable stats in bar

Hello, I'm trying to figure out how to setup a Journal entry with associated token that would roll some various stats when it's being created (dragged from Journal section to the map). Example: I have a generic Orc entry that has a HP value of 1HD, which means 1d8. My goal is to have this value rolled and displayed in the token's Bar, ideally with the current/total set correctly so the visual bar on the token represent the value correctly. This means that if I drag my Orc 3 times it would like to have the HP rolled separately for each token I set on the map and they would all have full HP (example 1/1, 5/5, 8/8). Is this even possible "on token drop" or do I need to get a separate macro for this?

Unfortunately, that requires the API, and a Pro subscription. The command would be: !npchp <character name>  - Rolls NPC hit point totals using their formula and updates the token bar. If no character name is provided it will roll the selected tokens.
