Ability to assign the fixed asset to the service contract as recurring fees are based on the asset

Hi

Client creates lease contracts in contracts. In order to keep history of the lease contracts assigned to a specific asset, they need to be bale to assign the asset to the contract. I noticed that it's possible to assign the maintenance asset to a subscription, but client wants to assign the actual fixed asset to the respective contracts. Also there is no integration between subscription and contracts as both options have the ability to generate customer invoices.

Is there standard functionality available to assign the fixed asset to the service contract?
