Dear Mench_956
Good day! Thank you for posting to Microsoft Community. I am happy to help you
According to my testing and investigation, there is no setting in Word that can automatically change the number directly.
You may need to automate this using VBA code or PowerAutomate, otherwise you may need to make changes to the format manually. For you to be assisted properly, please reach out to Forums | Microsoft Power Platform Community; I am sure that our experts from that team can address your query effectively and accurately.
Thank you for your cooperation and understanding. Please do not hesitate to post your queries in Microsoft Community and we will always do our best to assist you!
The reason I ask you to post a new thread is that in Answers forum, we have limited resources and very little knowledge about PowerAutomate and in Forums | Microsoft Power Platform Community you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction.
In the meantime, I will keep this thread open and welcome other users to share their experiences.
Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
