How to create several words autocomplete markup macro?

I am wondering whether it is possible to create a several words autocomplete dropdown macro. This several words, sure, are supposed to be marked previously.

I open a txt file which says something like:
“The green table is cheap. This table is nice.”

While I am reading the text, I select with the cursor “green table”, press some hot key XY to remember it for further autocompletion and “green table” is enclosed into an custom xml tag:
“The green table is cheap. This table is nice.”

Then I read the second phrase and come acros “table”, I highlight it with a cursor and again press the same hot key XY, this time, the macro offers me the list of all phrases that were mentioned before and enclosed into …, if I press ESC on the drop down, it marks the table in the same manner as previously “table“. If I choose something from this dropdown, it memorizes “table” for further dropdown and transforms the second phrases as follows:
“The green table is cheap. This table is nice.”

Can any body help me with this list?
