Powershell Clear-Host alternative to preserve the buffer

问题

I would like something like Clear-Host, but would like the scrollback.

So far, all I have is basically adding newlines until the screen is clear. Though when I do this, the cursor starts writing at the bottom of the page (as to be expect- though not desired).

I would hope to start writing at the top of the page (for menus and such- which is the natural thing to do)

This is the code to print the dynamic count of new lines:

do {Write-Host ""; $i++}
while ($i -ne $Host.UI.RawUI.WindowSize.Height)

I did see something about a Transcript module, but do not desire that.

Thanks in advance.
