[Liquid Dropping System] Refill tanks programmatically?

I’m wanting to know if there’s a way to refill the liquid dropping tanks using code rather than being forced to use the EFB tablet or scoops.
I can’t seem to find any simvars or evendIDs tied to refill of the tanks directly.

I am also aware that they can be filled using the FLT files (but I’d still like an event that can be trigger with javascript or xml). Thanks!
