A "configurator" App looks beyond WiX's feature set alone. Calling  a series of specific render images according to users progress through the step-wise specification process needs hand-crafted html code but a critical limitation is the context of the WiX html widget for embedding html. It can only reference external resources and not local WiX media already uploaded by the WiX site owner. A workaround could be to store such images externally such as on Instagram and reference them programmatically with the html. Very clunky. PARK!
