Remembering paired central information from peripheral.

I'd like to make a BLE Accessory(Peripheral).

iOS App of iPhone A and iPhone B is central.

Scenario is as following.

*Pairing a Accessory with a iPhone.

1. (Accessory) Adverting.

2. (iPhone) Start Scanning and Request a connection to Accessory.

3. (Accessory) Push a button to establish a connection and store the central info.

4. (iPhone) Disconnect a connection when away from each other.

* Re-connection

1. (iPhone) Start scanning and Request a connection to Accessory when closer to each other.

2. (Accessory) If the central is stored, establish a connection.

Is this proccess possible? this needs to allow connection by pressing a button and store the central info.
