SecureCRT, screen display only 'pattern' matches?

I can use Perl to spawn a router session, select only the pattern matched lines I want to display on my terminal.

Is it possible to have that same control when using my BUTTON assigned scripts.

Directly below, is an example of a BUTTON assigned script that will issue a command to the router, then display all the lines received.

At the end of this post is an example Perl Script that will only show me the pattern matched lines I am interested in. Since I can't get that to work in SecureCRT, that Perl example is reading a log file.

Can secureCRT moderate the output to the screen?

SecureCRT: BUTTON assigned script
# $language = "PerlScript"
# $interface = "1.0"

$true = 1;
$false = 0;

$vlan = $crt->Dialog->Prompt("Enter your VLAN ID: ", "vlanid", "", $true);

$crt->Screen->{'Synchronous'} = $true;
$crt->Screen->Send("show router interface to-7705-$vlan detail\015");
Perl Script: Only displays lines that match a PATTERN
my $filename = 'C:\tmp\LogFile.txt';
open(my $fh, '<:encoding(UTF-8)', $filename)
or die "Could not open file '$filename' $!";
while (my $row = <$fh>) {
chomp $row;
my $string = $row;

if (defined($string) && ($string =~ m/# show router interface/)) {
print "$row\n"; }
elsif (defined($string) && ($string =~ m/Admin State :/)) {
print "$row\n"; }
elsif (defined($string) && ($string =~ m/Description :/)) {
print "$row\n"; }
elsif (defined($string) && ($string =~ m/Port Id :/)) {
print "$row\n"; }
elsif (defined($string) && ($string =~ m/MAC Address :/)) {
print "$row\n"; }
close $fh;
