Hi Tharuna,
Thanks a lot for your answer

Ok, i have understood how to work on one table, that's a really good feature !!
So, your answer generate 2 other questions !
1 - Is there a way to work on several table with one process (modify a table and another one with a relation) ? If not, can i "link" to template to modify the first table and the second ?
2 - Is there a way to ask to your team plugin for specific component ? Here, i ask for DPCalendar, but there is so many extensions.. Maybe, there is a way to create our own import export "complex" templates or plugins ? Some documentation for this exits ?
Thanks a lot for your support Tharuna,
Best regards,
Xavier
