Bump location reassignment in LayoutXL

Dear all:

I am manage bump location on Layout XL. My case is there are hundreds of bumps with there own coordinate.

Now I want them to be relocated to their own new coordinate.

Is there any way to import a file which specified coordinates then all bumps' coordinate will be updated afterwards?

Please let me know any possible way to do this in cadence environment. Thank you in advance.
