Currently, the “Archive” option only appears when selecting "point" as the area of interest, which makes it easy to overlook for users who create requests with “line” or “area”.
It would be really helpful to add this earlier in the tasking flow, perhaps with a note or visual cue indicating that archive imagery is only available for point-based requests. Also, a guide or help doc outlining how to access and purchase archive images could go a long way in making this feature more discoverable and user-friendly.
