MATLAB: Tables: Left Outer Join without changing key names

join;table

Suppose I have two tables:
a = table({'a';'b';'c';'d'},[1;2;3;4],'VariableNames',{'Key','Var1'});
b = table({'a';'c';'e'},[0.1;0.2;0.3],'VariableNames',{'Key','Var2'});
And I do a left outer join:
c = outerjoin(a,b,'Type','left');
This will give me a table with variables 'Key_a', 'Var1', 'Key_b', 'Var2'
But what I would like to have would be a table with only 'Key', 'Var1', 'Var2'
Is there a simple way to do this via option settings, without having to rename manually? For me this would be a hassle, because I have tables with 7+ keys with dynamic names.

Tell outerjoin to merge the keys.
c = outerjoin(a,b,'Type','left','MergeKeys',true);
