Dissolve Polygons and generate list of those if the attribute value is different

Hi all,

I have overlapping polygons and I am using Dissolver to avoid this. However, I would like to keep some attribute from both polygons that are overlapping in case attribute value is different. For example, those polygons have attribute calls "Side" and i would like to have list of these in case of both polygon has different value for it such as Side = W and Side = E but if both attribute Side = W and Side = W.

I want to do it because in some cases i have 6 polygons are overlapping and if i generate a list regardless from the values of those attributes, I am having very long attribute list.

Thanks in advance.

Best
