Issue with the TestRail importer

Hello.

I'm in the process of moving from TestRail to Zephyr Scale.  I have several multi-line text field data type fields in TestRail that I'm trying to map.  One to an existing multi-line field in Zephyr and the others to custom fields of that type I created in Zephyr.  When I use the TestRail importer, the mapping screen considers the fields on the TestRail side as a single-line text field data type and won't let me map to my fields in Zephyr.

Does anybody know a workaround to this?

Thanks,

Rob Kubitz
