Set a filter on a layer in the mergin app

It would be really great if there would be a possibility to set a filter on a layer in the mergin app and change it spontaniously in the field. E.g. I have a layer with field parcels and many owners and in the field when I visit one owner I just want to see the parcels of this one person in the map, when I visit the next owner I just want to see the parcels of the next one and so on. For just small filter attributes (< 10 different attributes) it is fine to use themes in desktop QGIS, but when I work with bigger lists it would be helpful to switch it directly, at least for one field.
