Using DirectXMath and its XMMATRIX structure in C++ and Direct X 11, how does one multiply that matrix structure by a single float scalar?

I want to implement the operation B = A * f; where A and B are XMMATRIX and f is a float.

I found all sorts of functions to multiply a matrix by another matrix or a vector. I found all sorts of functions to construct matrices.

I could find no scalar multiplication! Why is there no such function? Is there no use case? Did I miss something? How do I implement scalar multiplication?
