Reference an existing PowerBI data source column in a SQL source

Hi all, new here.  I tried searching and couldn't find quite what I'm looking for, maybe because I'm trying to do it wrong.

  Tips and Tricks

I created a small table in powerBI where I manually typed in some stock tickers.  I used an API to pull some stock data for those tickers, that all works.

Now I'm trying to pull some of our data using a SQL query.  Our data is rather large, so I don't want to pull in the entire thing and then create the relationship, I would really like to join on the stock ticker table that I created in powerbi.  I managed to make it work using:

#"Tickers" = "'" & Text.Combine(Table.ToList(Table.SelectColumns(Tickers2,"Tickers")),"','") & "'",

And then editing my query to include a:

"...AND Ticker IN (" & #"Tickers" & ")"

But that seems a little silly.  Is there a "proper" way to do this?
