Ask your FFL. Most will do it. Some might charge extra for storage though.

I guess my question really is - Are FFLs required to start DROS within a certain time period from receipt of a firearm?

There is no requirement that a FFL starts a DROS withing a certain time period, so as was said, you need to check with the FFL to see if they will do it and what, if any, the charge will be to store the firearm.
