Using another column's value as property from same database

I have create a dataset with 2 main columns, tag name and tag path

The TAG_PATH column has value of the tag name (value from NAME column) in it.
Can I use the column NAME as property in cell binding for column TAG_PATH?

Something like,

where {NAME}[0] is the 0th cell under column NAME

No, cell update bindings cannot do indirection or expressions. Just direct tags or properties.
