Is there some way to keep a layerset/edit user defined within a QGIS project and/or templatevariables with a model or a calculator so that it is always available to hold commontheir values that you want call on for everycan be read by all the layouts and reports in a project? I have looked into virtual layers but they are not editable once created. I do not want the file to be external as it is to be changed oncecalculate a project reference point whose values can appear in all title blocks in various scale maps in the new project is defined. And, the variable names will remain in the project template and recalculated for the next project etc.
