'growing files' Formats/codecs that Premiere pro supports?

Last night I was editing with a 'growing file' from a live feed supplied from the EVS system at the network I was at. It encodes to DNxHD 120 and this worked fine in Premiere Pro 2019 except occasionally Premiere would no longer 'see' that the file was growing. Quick app restart solved this.

My question is, where can I find a current list of the formats/codecs that Premiere Pro supports for 'growing files'. The only Adobe document I found does not have DNx on the list - yet DNx seems to work fine:
