I do the same. I have no slabs, only albums.
Might I make a suggestion. You said you tape the slab lables to the inside cover of the album. The problem is if you change albums, this is a pain in the you know what. What I do is on a sheet of paper the size of the album, I title it slabbed coins. Then using those pieces of paper that have that sticky stuff on it, I tape the slab labels to those and then stick those on to that added on sheet of paper and that is on the front of the albums.
Now with Whitman, there is always a sheet of paper advertisement inside when you buy one new. It is on the front of the pages. If that is present, I use that for the sticky paper with the lables on it.
The purpose of all this is if you change coins in an album, you can just peel off the associated sticky paper with the associated slabbed label and move it to the album with the coin.
This may not apply to most people but I have, for example, 12
Mercury dime Albums, 10
Lincoln Cent Albums, etc., etc., etc. I find myself many times over the years moving coins so my system is great for me.
