I'm affraid that I don't really understand exactly what you need.
There is a relationship between the take off CG and the take off pitch trim setting. This relationship is constant for a given airplane (there can be differences between models). This relationship is given in the THS wheel itself and in the normal checklist. It is also shown in the balance part of the load sheet.
If your airplane does not use the checklist, nor the THS scale, then they must have manual load and balance sheet. If that is not what you are looking for, there is nothing else I can do...
