Feature Request - Assets Tag for Equipment (Supported, EOL, Leased)

How does everyone keep track of clients equipment and EOL dates?

For example you have a client who has a EOL Switch and WAP. They have decided against upgrading it in the past.

You have different SLA's on EOL equipment.

Where do you document in IT Flow that equipment is EOL?

I really like the idea of TAGS for this on the asset scree, but wondering what everyone else is doing?

I like the idea of asset tags, we'll add this in the next stable release
