Hi all , great site 1st post. I'll try to be as concise as possible. I want to add 2 sets of recessed cans on dimmers to existing 2 gang box. I want all 4 switches in same box because of location & convenience. Obviously i have to replace 2g box with a 4g box , rewire 2 exisiting switches and wire up 2 new switches , pull wire and install cans. My question is , for ease of wiring , can i use a hot lead pigtail to wire up the 2 switches on far end of 4g box?
