Change SIP trigger date

I have 2 SIPs triggering every Friday of the week. After initial observation I want, one of them to be executed on Wednesday. I can’t find option to change that. We have option to change the frequency or pause the SIP but nothing on shifting he triggering day. Please let me know, I am a newbie.




You can stop the SIP and place it on Wednesday, after that the order will be executed after every 7 days.
