Can I Have My Hair Character Changed During a Transplant?

I have wavy hair and would like a hair transplant but I prefer FUE so I don’t get a scar at the back of my head. I understand that the hair shaft slightly curls under the skin for wavy hair. Once my hair is extracted via FUE is it possible to implant it into my thinning area but make the hair shaft or bulb of the hair straight so I have straight hair growing out instead of wavy. I know it sounds weird but can it be done?

I had a patient once tell me that another doctor he saw for a consultation had told him he could have his hair character changed from curly to straight, but the surgeon has no such control. If a surgeon tells you he/she does have that ability, run away, because he may have other personal reasons to do your surgery ($$).
