If you don't want to be doing that each time you cold start the car the only other options will be to either remove the cold start with a tune or to take the sport cat off. Re-adding the oem resonator won't help.
Can you explain this option further? My assumption is that the car starts in comfort with valves closes but maybe the valves open for cold start?

1. Close valve(s) ( I have a CG VSC-1 valve controller)
