Current behavior

The Contacts page only offers 20, 50, or 100 rows per page, and selection is limited to what's visible on the current page. On a sub-account with 8,000+ contacts, a filtered list can run 400+ pages. If I need 5,000 contacts, I have to page through 50 pages at 100 per page and re-select each time.

Problem

There's no way to act on a large subset of contacts in one pass. This makes bulk tagging, bulk workflow adds, exports, and campaign list building extremely slow and error-prone one misclick or accidental page refresh and the selection is lost. Anyone managing high-volume accounts hits this constantly.

Requested enhancement

Custom page size let the 20/50/100 dropdown accept a typed value (e.g. 500, 1000), or add larger presets.

Select a specific quantity, a "Select first N contacts" input that selects N records from the current filtered/sorted result set, spanning pages (e.g. "Select 5,000").
