How to select objects under visible VUE markers?

Hi,

I am using synopsys ICV for validation, and synopsys VUE for loading error markers. Is there a way to select a particular object type (eg: all via1) under the currently visible markers?

I need this to change the gray colored metals to either color A or B.

I would be really grateful if you can suggest a way to automatically color every via that is generated by the automatic via generator, in which case I do not need the solution for the first question.

Thanks in advance,

Jinesh
