Trying to change Collabora document default settings

I am seeing that by default Collabora file types are opening in A4 page size and measured in cm. Is there an easy way to switch the default to Letter format and measurement of inches? I feel like I’m missing something very simple here.

Hello,

I have not found a way to set the default as letter but you could use templates to archive this.

for the measurement you can just simply type X in for example 10 in it will then calculate it to 25,40 cm so you can use inches by ending your size with in but all is shown in cm.

Sorry to bring you sad news, hope it helps you in anyway
