Two layers keep your alerts focused:
In Settings you can add rules that send matching products to a specific destination. For example, route anything containing "dunk" to a dedicated Discord channel, restocks only. Each rule matches on keywords, monitors, and event types.
Instead of ticking monitors one at a time, point a keyword task at a monitor group. Groups stay live: file a new monitor into "Pokemon retailers" and every task scoped to that group picks it up immediately, with nothing to re-edit. Individually picked monitors don't work that way, they're a snapshot of what you ticked on the day.
You can mix the two. A task can watch a whole group and a couple of extra monitors that sit outside it.
