[TTyo]

Load 5000 items into table. Iterate over 4500-4900 items and make new table. Set new values.

Or. Load first unnecessary items (4500) - remove it from result list. Load need amount (4900 - 4500 = 400 in this case) and use editAll to set all values at once.

In any case you must able program in Lua and understand code and API. Read docs and learn lua.
