Change default Downloads folder in Edge

The methods described here (whether they work or not) seem quite unacceptable. Both appear intended to allow the destination to be set to *one* non-default location at a time. A clearly desirable option is what Chromium, and I think Firefox and possibly others offer: a pop-up, prefilled with a default that can be overtyped and containing a browse button to choose a different location.

My particular use case is that I want to save the installer or software for third party products (e. g., Garmin Training Center) somewhere other than the default folder in which I would save documents downloaded for later reading.

Unless this is added by release time I will not be using Edge and expect to have some company.

Observation: In Internet Explorer, when you click on a .pdf, Word, Excel, etc.. file link inside of a webpage, the document opens in your chosen default application.

Question: Is that document/file saved someplace that's invisible (maybe a system TEMP folder?) unless/until you choose to save it to a specific folder for later retrieval? In Edge, every time I open a link to anything, that item is saved to my "downloads" folder. I don't want that. If I don't intentionally save the file, I'd rather not ever see it again. I'd rather have Edge work like I.E. in this regard. Is there an easy way for casual users to do this?

FYI Update. Tonight, I was astonished to find over 300 .pdf files filling up the folder that I use for saving downloaded software for execution. All I've done is opened and read them, in connection with my job.

Just chiming in here to say "Thank-you!" Brink for posting a detailed forum tutorial describing how to change the default download path used by EDGE. Now, these .pdf's will be downloaded to my User/AppData/Temp folder, just IE11 used to do, I think. Anyway, each run of CCleaner should whisk them away, as it did in Win7. Thanks again!
