HMI tags Audit

We need to control 450 fans from this HMI, with each fan requiring 15 tags. This configuration exceeds the tag limit. Using indexed tags resolves the issue; however, during audits, the same tag name appears for all fans. How can we differentiate audit events for each fan? Is it possible to update tag names from the HMI to improve audit log differentiation? Index tags screenshot attached. Attachment Index_HMI_Tags.png (28 Downloads)
