You can apply conditions to terms in the Glossary Editor. See How to Apply Conditions to Glossary Terms.
If you want to apply the same condition(s) to multiple terms, hold down your SHIFT or CTRL key and select the terms. Then right-click and select Properties. Then on the Conditional Text tab, choose the condition(s).
A Condition column in the Glossary Editor indicates whether a term has conditions applied to it.
