@ Mention does not list all options

A few times, I have tried to @ mention a task, however the list is limited to a list of most likely options and in these cases, the task I would like to mention was not there. I was not able to narrow down the list no matter how many times I prompted the list with new variants.

Ex: I wanted the Task “CAP” and tried the @CAP but the list revealed many of my other tasks including CAPA_XYZ, CAPA_ABC, CAP_V, Capstone, Capillary, Capone and Noreaga, … you get the picture.

As I mentioned, this has happened a few times, and it would be nice to be able to enter clues to the Project or something to narrow down the list to find the task we are looking for.
Thanks
