No more bits for in line network attribute

[PierreloupDucroix]

Hello,

I'm trying to add a network attribute inline, but I'm getting the following error:

Error 001953 The length of the selected domain exceeds the number of bits remaining for the inline attribute.

Indeed, it seems that I've reached the 25-bit limit for user-defined attributes in my UN:

How can I get more bits, either removing a network attribute, or removing the "In Line" properties if possible.

Thanks
