I use sliders to make streams :p
Ctrl+ Shift + F to convert a slider into a stream.
There would be 3 options on that (by object count, by distance snap and beat snap divisor).
By object count it would make your slider into the selected amount of circles (If you put 5, then the slider no matter the size or lenght it would convert into a 5 notes stream).
By distance snap it changes the spacing of the premade stream of the slider (you can make it wider or narrower depends on your preference :p).
And beat snap divisor change the beat snap divisor of the stream (it is 1/4 by default but you can change it to 1/1, 1/2 or 1/16 if you want xD).
I hope this could be helpful to you and sorry for reading the post so late qwq.
