Saving the filter list for use and adjust in another project

sorry for my imperfect english
currently we have icons copy and paste in the list of filters, but to copy in another project is not easy, especially if you want to quickly change the filter settings, could we have two more icons for export the contents of the filter list to a file instead of the clipboard and be able to reload it in the clipboard from the file

actually we have :

I know we can make the clip in a new project, add some filter save it and then open the mlt in another project but if we want adjust the filter setting we need to save the project, close it, open the clip, adjust the filter, save it reload the project…

I think that would be a really good addition - very useful.
