Only if you were grandfathered in and have been associated with II (not RCI) since at least 2014. If you are one that can do it, you can't deposit with RCI and Wyndham has been making it difficult to continue with II for those grandfathered in so most have just switched to RCI. Since the program fee includes the exchange membership, they really don't want to pay that to a Marriott owned business like II, they want to keep that membership fee and then any associated exchanges or getaways in the Wyndham owned RCI.
