Currently its possible to filter Upwell Structures only by type (Citadels, Engineering Complexes, Refineries) and not by size (M, L, XL). So for example you cant have only Fortizars displayed and all Astrahuses and Keepstars hidden. Dunno what best approach would be to solve this, if adding size option to overview settings or display all structure names there (there is currently only one type of each).
thx for reading
