I am not sure if this is the most efficient way of doing this, but you
can store the block value in a variable and remove the complete attribute
followed by re-adding the block value.
Yes I thought about this way to do it. But there are lots of properties linked to Attribute to be copied ( value, position, size, font, visibility, color, ... ).
I hope there is a more efficient way to do the job.
Thank you. Best regards.
>>How can I remove this instance ? I don't find any function to do so.
I solved this Issue deleting the Attribute and readd it.
Maybe some more steps but it works.
