While you are waiting for a suggestion to be approved by Julie, you can "force" an annotation on the annotation fields where the ECV is being used (the right and left hand ID gloss tiers). As explained in the ELAN manual online
, "it is possible to by-pass the controlled vocabulary constraints by holding shift and double clicking on the active annotation (right clicking and selecting “Modify annotation value” while holding shift does the same)."
On this annotation field, enter ~NEEDS-IDGLOSS (replace that with an actual suggestion if you have one). (This is also in the SLAAASh manual - "new ID gloss needed" - section 4.2.16 and table of all conventions at the end of the guide).
