how to convert a bar in 3/4 to a bar in 2/4

Happy New Year and thank you all for taking the time to reply to my post. Apologizes if i was not as clear as i might have been. I have found the solution i was looking for, which i will explain in a minute:
1. I have been working on classical guitar Etude VI by Leo Brouwer, which covers arpeggios. The version i have suggested that other variants on the etude are possible and includes 6 single bars which point to how the variants can be expanded. I have managed to write out the first variant and was stuck on the second, which challenges the player to take the first variant (the one on the screen marked '1', which is in 3/4) and change it to 2/4 and 2 groups of Sextuplets.
After checking all the videos i could find, i came across the solution, which is the following:
1. I changed the first bar from 3/4 to 2/4
2. I deleted all the notes and created 2 Crotchets
3. I used the menu: Add-Tuplets-Other
4. I changed the Ratio to 6/4
5. This created 6 semiquavers grouped in the time of the Crochet
6. I added the notes, flipped the direction and checked the beam was correct and that did it.

I hope this may be useful for anyone else trying to do this type of thing.
Thanks again.
Regards
Pedro
