Tagging content imported via TAXII Feeds

[ptrac3]

Hi everybody!
I was trying to import custom feeds into OpenCTI and, although that worked, I was trying to find a way to tag the imported feeds somehow. For example, I have managed to import a TAXII feed regarding Tor's Exit Nodes (DAN Tor) but the created indicator is "None".
The problem is that if I add multiple blacklists etc. there is not going to be a way for me to discriminate between those.. Is there a way to "tag" the imported contents automatically? So if I create a TAXII - INTEL connector I would like to know that the info was gathered from that connector.
