How to automatically substitute matched text with Rem reference

Sometimes I create a Rim reference. and later on, I reuse the same term and I forget to link it again to the Rim reference.

What I need is that every time I use a word that there’s a Rem Ref with the same spelling to substitute automatically or at least suggest to link it with the correspondence Rem ref.

Example: I have a rem titled “computer parts”, and in this rem I used the word CPU. I rem referenced it using [[CPU to describe its meaning.

I want later on, every time I write the word CPU to be automatically referenced back to the first rem ref -[[CPU- created.
