When importing an instance into VEP, if the imported instance includes a channel that uses MIR as an insert, the current VEP/MIR project changes to the venue of that imported channel/instance. This means that the importing instances functionality is impractical when using MIR.
The preferred behaviour would be that the imported channel/instance is instead loaded into the current MIR venue. And if multiple venues are being used, load the channel(s) into the first venue.
