Currently, when using a custom field to link tasks, it is not possible to limit the link:

or to a single specific list,

or to all the lists of all the tasks.

This logic is too restrictive.

Desired evolution:

Be able to select several specific lists (for example 2, 3 or 4), and only allow the link to the tasks contained in these lists.

Expected benefit:

More flexibility in the organization of projects.

Reduced risk of error by limiting links to lists that are really relevant.

Save time in the daily management of tasks.
