I thought so already. This is why I don't like to have to send multiple 
requests to do one thing (transaction). I'd rather be able to send one 
request to both do, say, an update and return a result, or add a 
document and return a result. The system so far doesn't allow me to do 
this, because I cannot define one query (or function in a module) that 
does both because of typing restrictions, and I also cannot send two 
separate queries in one request because of restrictions in the XRPC 

Any thoughts about achieving what I want?
