Long answer, it can but with more workarounds, that will slow down even more, so being in no code, we need to really pick the features carefully, adding more visibility to component inside the list will add more burden, this is probably not seen in high speed internet near the cloud server in US, but for the rest of us, it is not worthed.
If you have a sequential count of messages for that conversation, you can use the message # as a filter to hide the created date/time on previous messages.
Select your created date text component and set the visibility to Sometimes Visible if > Current conversation > Message Count > is equal to 0. Add a custom filter where message # is greater than current message > message # and another custom filter where current message > sending user > email > is not equal to logged-in user email.
