Automatically subtract HP from monsters

Is it possible, if a player targets a monster, hits and rolls damage, for that damage to be automatically subtracted from the monster's HP?  
Only with an API script, which is a Pro subscriber feature.

To be clear: without API scripts, macros can only read data from a sheet, they cant change data on a sheet. So you can get the value of an attribute, and roll it, but you cant change the value of an attribute.
What API script?

You cant use an API script unless your GM is a Pro subscriber, but there are several that can change character sheets. ChatSetAttrs is the old standby. TokenMod is the swiss army knife for token manipulation.
