You can schedule the order action job at regular intervals to sort the list through an integration user who has Workspace Administrator rights. Meanwhile, have the project list sorted by the property (name(item("Project List")) while displaying to the end-user so that the end-user will see the correct Alphabetical order.
However, this cannot be used in dropdown selections
Thanks I cant basically make use of text based sorting because im using the default sorting to sort another attribute of the project, I hoped that the alphabetic sorting would be taken care by running an action. However, that does not seem to be an option now. Anyhow thanks for the suggestion
