Accessing Variables from Past Versions of PDL Data

Hi there,

I am wondering if it would be possible to obtain certain variables from past pulls of the PDL data to create a panel. Specifically, from the person-data, I am wondering if I could get previous versions of the skill data (to be able to decipher when people add skills to their profile). From the Company data, I am wondering if it is possible to get the size variable associated with a company ID over time to see when firms go from one size band to another. Happy to receive just Company ID, Size, Dataset Version, Estimate of Time Pulled to then create a panel myself. Please let me know if this would be possible!
