What's the equivalent to FOREIGN KEY & REFERENCES in Power Query to create relationships from code?

[ECorona]

I'm making a custom connector that consumes a rest API to create for tables that are in a linear way. The thing is that everytime the user loads the tables he needs to created the relationships by hand, so I'm trying to create the relationships from code using Power Query M to save time to my users. Is there an equivalent of MySQL's in Power Query M of this:

FOREIGN KEY (locationID) REFERENCES Locations(id)

So, my tables (reducing the example to only two tables): 

let
Locations= #table(
{"id", "location", "state","zipCode"},
{
{1, "Tehuacan", "Puebla","7200"},
{2, "Santa Ana", "Tlaxcala", "90300"},
{3, "Tijuana", "Baja California","22400"}
}
),
KeysTagged = Table.AddKey(Locations, {"id"}, true)
in
KeysTagged

let
Products= #table(
{"id", "date", "product","quantity","revenue","locationID"},
{
{1, "2/8/2023 9:30:10 PM", "Zapatos",10,5000,2},
{2, "4/18/2023 8:24:12 PM", "Cinturones",10,5689,2},
{3, "8/12/2023 4:08:23 PM", "Tennis",10,3467,3}
}
),
KeysTagged = Table.AddKey(Products, {"id"}, true)
in
KeysTagged

Power Query does not have such a concept.  All partitions are independently loaded into VertiPaq.

What you can do is name the join columns the same and hope for Power BI to make the right guesses.

You can also experiment with Table.AddKey and Table.Keys  to help with the suggestion.
