**Feature Request** When I'm working with multi sheet schematics and I already have prefixes C1-C10 in use in sheet A and I place a new capacitor in sheet B, the schematic editor starts naming from C1, meaning that there will be conflicting prefixes in sheets A and B. I need to manually changes all the prefixes is sheet B to non conflicting values. It would be better if the prefix name space would be automatically shared with all schematics sheets within a project, i.e., when I add a component, the schematic editor would check all the sheets to find out what is the first unused prefix value. Thanks for the great tool!
