Is it possible to use two integrations in interface having one editable grid

For suppose we have two drop down fields F1 and F2 in an editable grid. And we have two integrations namely A and B.  

A contains data of F1 and F2 fields we need to fetch data from integration A and displays the data in each row as soon as interface loads.

And by clicking add new row link in grid .the field F1 as it is drop down we need to fetch the dropdown values from integration B

Let me know is it possible if yes any helpful tips to solve this.
