force a rescan of a read-only selective-sync destination folder?

Hi, I'm a huge fan of RS and have been using the PRO version for a while now. Thanks for a great product. After doing a factory reset on my phone I'm setting up my RS folders again but I've read the help and forums but can't find an answer to the following situation I'm in.

Situation: I have a Sync folder containing the iTunes music on my Macbook and I had used a selective-sync read-only key folder on my Android to pull many GB of files that I wanted on my external SD card. I was hoping that when I setup the selective-sync folder again on my Android that RS would recognize the many GB of files that were already on the extSD card but it doesn't notice that they are there. Normally when I use an existing folder Sync recognizes that the folder isn't empty but it didn't ask me about that this time when I configured the folder. I assume this is because it's setup from a 'read-only key.'  

I'm hoping that there's some way to force it to do a rescan of the folder (rescan what is synced to the Android extSD card, not a rescan of the source) to update the 'synced' file counts and GB count. Any ideas?

Hi, can anyone help me with this? Is the question clear?

that's how RO + Selective Sync work. Option to "overwrite any changed files" is always enabled, thus when you add the folder to Sync on phone again,  synced files are overwritten and replaced with placeholders.
