[Question] Is it possible to start a plugin manually, then use ReattachConfig to connect to the running process?

Everything I can find/read related to reattachconfig usage (I dug mostly through Nomad) uses the reattach config to connect to a previously executed process launched from the main process.

My question is, could I manually exec a plugin somehow, keep it running, then manually configure the ReattachConfig to connect with that plugin? Any pointers would be much appreciated, thanks!
