Is possible somehow let's say visit card duplicated 12 times on sheet, by mistake typed a wrong numb. and retype on one to effect all cards?
This may be possible. You can use edit > find and replace > replace text and then fill in the old and new strings.
But as always with this type of replacement, you have to be careful to verify that only the required replacements take place. For example, if you asked to replace the street number 23 with 123, you need to make sure that 23 does not also occur in a phone number or postcode.
This is relative with your workflow. There's two ways to create 12 cards:
1 - Create ONE card, set up the page at the real size of one card. Then go to Print Peview and choose the imposition you want with the second tool (imposition tool).
2 - Using a macro such as Oberon Object Tiler

both ways allows you to create all cards at the same time
To bad is not like some kind of template and than duplicated, not that happend all the time, but when happend !
Sounds like a good time to use the "clone" instead of duplicate. Create one card select all then Edit/clone . Change text on the original and poof all the rest are changed. Can't move items though.
How can be set offset for clone?
Image is really shifting strange !
Now after restarting pc image is shifting OK !
