tuplet in irregulars bars

Hi,
I have a 7/16 time signature bar, and I’d like to have a rhythm of 2 notes in the bar. I know I could write 2 double-dotted eight notes, but is there a way to write it in a quarter note tuplet to make it more easy to read/feel ? I can get this result in 1/32 notes, writing a tuplet of “2:14”. But if I try to do it selecting quarter notes, and entering “2:1.75”, the tuplet seems to end further than the barline.
Thanks and sorry for the mathematic headache :sunglasses:

If you set the duration to 1/16.
Enter 8:7 in the popover.
Force durations.
Enter two 1/4 notes.
