Comment 4 for bug 1794072

Just a copy-paste of my answer posted in the mailing list:

I was thinking on something like: `File > Import`, and once the "PDF import Settings" menu pops up,
I was thinking on a simple "check option" that, when checked, it would automatically write the path of the imported figure (/home/user/path_to_the_figure/figure.pdf) directly onto the "Href" field under "Object attributes" (for instance, or in any other place).

Once the project is saved and closed, the user can re-open the project, do right click on the figure, click on "Link properties" and view the path for the imported figure in the "Href" or title tag field. Then go to that path and modify the gnuplot or python scripts that generate that plot.
