How to import a .tif stack as a video?

So I do have tif stacks that I want to import into DavinciResolve. However, this seems only to be possible if they are split into individual files, that end in a sequence of numbers. Then Davinci recognizes them as a sequence and I can import them. However, when I just have a .tif stack with the same files it does not show it as a video, but only as a still of the first frame.

How do I import a tif stack as a video instead, without having to change the file?

I'm thinking you can't, and your current method is the only way.
