Is "However so" an acceptable phrase? [closed]

I had a question about the phrase "however so". Make note that I am not talking about "... however, so ...".

For example, The sentence I want to write is:

Bob told me that we can tweak the document however so.

The meaning I think/want "however so" to conveys here is: "Bob told me that we can adjust the document in any way we want".

I was wondering if anyone else had seen "however so" used in this way. It seems familiar to me to use it, but something about the natural flow sounds extremely awkward to me, and I don't know why.

Has anyone encountered this usage before?

Thanks

That's an odd way to end a sentence. However so you choose to write it, I think it is unclear and therefore not the right place to use these words.

Note in the previous sentence I could drop the "so" with no change in meaning. The explicit "so" is not required in modern English.

For instance, "Like to the rain" is an archaic way of saying "Like the rain." Although it's not required either way, the "to" is in modern English implied by "like." We do not say "the iPhone 6 is like to the 6XS but with a smaller screen."
