I would like the ability to import non-public WDLs. Currently only public WDLs can be imported.
I'd like to second this request. See @ruslanafrazer 's support thread https://gatkforums.broadinstitute.org/firecloud/discussion/15313/workflow-imports-do-not-work#latest
Until you add support for importing non-public workflows, it would be very helpful if the documentation stated the current restriction.
