For those of use power users...we like to be able to bulk import the URL's and not be able to do it one at a time. Ver 4 you could do that in either the adlist.list or from the web GUI. No easy way now to bulk import the URL's... 
Yes but that means taking all the URL's from other sites and manipulating them with notepad ++ or other editor so its one long string instead of individual URL's as was in the past.
It was easier to just cut and past the URL's from WALLY3K and place them in either the adlist.list or web gui.
This is not the case.
If you go to a site where there are a number of URLs on a single page (i.e. the Wally3K ticked lists page), all you need to do is select all, copy to clipboard, and then paste into your dashboard entry page for adlists.
Note that the database entry process checks for duplicates, so if you already have one of those lists in your gravity database, the import will fail and you will get an error message.
You can still do this in the web GUI, as noted above.
If you are only checking for new or changed lists, then you will need to adjust your strategy to work with the new gravity database. Examples of how to enter items in the database are contained in this part of the Pi-hole documentation.
I will need to validate that. I was under the impression that the WALLY3K list had carriage returns in it and you had to clean those out to make the line look as a single line.
Just tested this on a Mac. Selected the Wally3K ticked list page, highlighted all URL, copied to clipboard. Pasted directly into the Adlist Group Management window. All added with no problems.
Thanks! That makes things a little simpler. May have a few more blocklists to add later one so its good to know.
I am running a cron that will go out to the wally3k URL and just grab that and update the db in case something changes there. Found it on github....seems to work out well since I dont have to go to his site to check on the tick list now. The script will do that.
