I believe the poster wishes to have a url that, when clicked, will take them to a specific slide in the project rather than always the beginning.
Perhaps a large project with many sections and a person completes section 1 and we want them to deep link direct to section 2.
The below example is not an answer to this question but an example of how we see this sort of thing in other situations. The URL is modified by adding the ?page=17 to the end.
It is an interesting question - my gut says I don't think so but I could be wrong - I've never explored this idea but could see the usefulness of it.
I might suggest a large menu as your first slide for the learner to select the topic - or make use of the table of contents. I always prefer a homemade system of navigating and would opt for a custom menu.
