Is it possible to store interest-bearing tokens at the same address for different users within Aave?

Question

Example: User 1 supplied 100 USDT year ago and User 2 supplied 10 USDT month ago. All aTokens I store at the same address. In total - supplied 110 USDT and I have, for example, 118.56 aUSDT.
