For that case, there is a better UI idiom. You could let the user mark
multiple items with ‘m’, unmark with ‘u’, and perform common
operations on the marked items. For instances of this workflow, see
Dired, Ibuffer, and bookmark-bmenu-list.

The easiest implementation is probably still tabulated-list-mode and
you’ll have to implement marking, unmarking and
act-on-marked-items-or-item-at-point.
