Seems link doesn't work anymore, but I found solution on my own:
1) create a variable;
2) create input box with this var and specify one value for it there;
3) tick a checkmark Include in Bookmarks;
4) save a bookmark with desired selections and needed var value
5) optional - you can now even delete created input box. Bookmark is still remain with defined var value.
Next time you apply a bookmark - it will trigger a var to change to specified value.
After that you can link to that var everything you need.
