No it can be what ever you want them for in any mode. The thing this year is that CCM offline and online play differently. What may work in CCM may not in play now. Also IF you play a CCM in both you have to input them twice.
** WAIT UNTIL PATCH** for offline. The profile does not seem to save and CCM offline needs patching from what I hear. Playing online you get up to the minute tuners instead of waiting on patch. As long as you don't restart an online CCM after starting the season those sliders will hold and be there when you come back.
