Adding Collector based on fixed input collectorID via RPC call

All resource Ids are automatically set in LogicMonitor, because Ids need to be unique.  Automatically setting them is the simplest & safest way to enforce uniqueness.  We do, however, allow you to set Collector description.  You mentioned wanting to set Collector Id to better facilitate Collector organization - are you using Collector Groups?  Collector groups should enable Collector organization, and although our RPC API doesn't allow you to set/update Collector Groups for your Collectors, this functionality will be included in our upcoming REST API.  Our REST API for Collectors & Collector Groups is expected to be published in v81.
