Forms in PowerShell: Update form based on script progress

Question

Hello all,
For lack of a better post title, what I have is a simple script that loops through files in a directory and checks them for stuff. What I'd like to do is, while my script is checking the files, display a form with only one single-line field
in it, and that field updates with the current file variable the script is checking. This would kind of be like when you're installing a program, and in the installation window above the progress bar it has a single-line field where it lists
each file while it's currently installing. I'd like something similar, but I don't need the progress bar. I'd like to just have a single form and have only this single "file" field change, but I worry that I'll have to redisplay
the entire form in some kind of "loop" every time I want the field to change. I'd like to display the form once and only have the field change.
Has anyone ever made a form like this, or know of a way I can accomplish this?

[int]$PC=0                        # Percent Counter
[int]$PCINC=100 / $Files.Count    # Percent Increment Files.Count <= 100
ForEach ($File in $Files)
    Write-Progress -Activity "Processing $File" `
       -PercentComplete $PC -CurrentOperation "$PC% complete" `
       -Status "Please wait."
    #Some File Operation
    $PC=$PC+$PCINC
Write-Progress "Done" "Done" -completed
