Thread Subscription - different settings for starter and replier?

[Stealth]

While trying to set my thread subscriptions, I found out that I can only globally set the email notification type - either none or immediate/daily/weekly. Considering I use a forward-to-cell-phone mechanism later on in the forwarding chain, I was wondering:

Is there any chance I can set subscribed threads I started to one type (say, immediate email report), and subscribed threads I haven't started (but have replied to) to another type (say, no email report at all)?

Thanks in advance.
