Generally no, forwarding is the business of the receiver, and
the S in SPF is "sender".  In your special case that might be
somewhat different, because the forwarder is related to the
sender, but it won't work if e.g. I send a mail to your SC
address.

General solutions:  whitelist your forwarder (= don't check
SPF behind it, it works only at the first MX, not later), or
let your forwarder use its own "MAIL FROM" (same idea as for
most mailing lists).
