I wouldn’t do that if I were you. Standardized coefficients are overrated and mostly misinterpreted. For example, unless conditions are perfect, they do not tell you the relative importance of the predictors as many people think they do. What are the conditions, you ask? Uncorrelated, perfectly reliable predictors without outliers.

Subject: Z scores
Dear List,
I am running a binary logistic regression and I wanted to standardise the predictors beforehand by converting to z scores so that the regression coefficients in the output are standardised. However, some of these predictors are already standardised with a mean of 100 and SD of 15. Will SPSS convert these standard scores to z scores properly?
