You should be able to add linked processes within a task, you shouldn't have to add a note.
For instance if you had a process how to onboard a new staff member and there were technical steps to follow, however most users know how to do this so you want it for a few, there should be an option to have a process linked to tasks like notes.
With this you should be able to add text when linking a process, as sometimes it's an FYI or needs further instructions
Also when using parallel activities there you should be able to link to this within an activity. For instance activity 1.0 advises to follow 2.0 for X, 2.2 for X and 2.3 for X. To save the user needing to scroll in procedure view you should be able to jump kind of bookmark to avoid scrolling
