How are the asset named?

Why?
For a better usability we develop an external actor which reads over the blockchain data and for each Fixed Payout asset we take from the message body the pre-image of asset identifier and from this we formulate the asset name for both asset's positions. 
How?
Asset: 0000000062c2fc4b5c705a9afcfe90fdb8fca6fa34ac805f92f44beeeb3fd8a65c32f4b200741f70b7a0e492982df5c2fff6c056f58c0ffdc9e4f769a570cf45c9a4c6f3 has a long name AAPL070121H080121Bull11700 and a short name AAPLBull11700 they differ by the Start and End data in the Fixed Payout message body.
