Can .nsx and .TRC iEEG data be converted to BIDS?

We have iEEG data recorded using Blackrock (.ns2, .ns3, and .ns6) and MicroMed (.TRC) machines. After reading through the documentation, it looks like these are not listed as being able to convert to BIDS format. Is that something that is being worked on, or are there any resources for this?
Thank you!
