Can anyone tell me if it is possible (and how) to convert or copy a selection on a layer (that has not been created through "select by expression", but instead by irregular selections from a canvas, or a combination of methods) in to the filter/query builder.
OR: If i have made a selection of features not based on a "selection query" or "select by expression" process, but simply by selecting them from the canvas in an irregular fashion ... I want to know if i can take that irregular selection and turn it into a "filter"? (I know i can "save as" a new layer - but I am trying to avoid having to do that) by simply clicking a button/command or something similar and "pasting" it in the query builder to create a filter?
The benefit of this feature would make progressive/iterative selections of selections quicker and without having to "save as" lots of new files ... or potentially lose them if they are just memory layers.
... beyond progressive/iterative, the important thing is to be able to attempt various selections on an initial selection before been satisfied and moving to the next stage.
