Yes. You can dynamically change the address referenced by an object using the index feature.  This allows you to create and indirect pointer or offset into PLC or HMI memory. In the object properties window click on the address settings button then
check the Index register checkbox and select the index to use:

 

When you change the value in the index register the
address the object is pointing at will change.  If you have multiple objects all
pointing at the same index register they will all update when the index changes. The actual address is given by the address configured in the address bar + the current value in the index register.The value of the index register can be controlled with any object. Index registers are system tags. Index 0 is at address LW-9200.

This feature works with most address based PLC drivers.
