Is there a way to display in a legend of a lookup explo-date the explo length of the relative year?

I know how to do it via sql database query but not in tex. Not that I know of. This would be a nice feature to add for any of the lookup parameters. Ignoring coding, from a ‘clarity of functionality’ perspective, lookup scrap and lookup map would be straight forward. Lookup map would be nice when an output contains several caves. Lookups altitude, explo-date, topo-date would all be equally useful, but for user clarity when specifying, perhaps they should only be available when specifying an interval or band (as described in https://therion.speleo.sk/wiki/examples?s[]=lookup#colour_palette_scales_-_lookups <https://therion.speleo.sk/wiki/examples?s%5b%5d=lookup#colour_palette_scales_-_lookups> ).
