Drag the patterns on the song editor

Having trouble with LMMS? Ask about it here.
Hello,
Greetings from France.
Hope you will understand my "frenglish" :D
I'm a huge fan of LMMS that I use for a long time now.
I don't know if what i'm searching is implemented or not, that's why I ask for the question.

When I do a song, sometimes I want to put some patterns BEFORE the existing patterns on the song editor.
I didn't find a way to do it all at the same time.
The only way that I find is to change the place of every pattern, pattern after pattern.
When the song is "heavy", it's sometimes very tedious.
So... Is it a way to do it that I didn't find ( with the mouse, or/and with a keybord shortcut), or shall ask for an pull request in the github.

Thank you for your answer.

By the way, this one is done with LMMS and soundfonts sf2, for a contest on the french site linuxmao.org.

Welcome to the forum tenryu! First, For you all important links:

Yes you can move everything in song-editor both ways:

Right-ways:
Place the playhead a tiny bit before the place where you want all blocks to move from
Hold Sh + press insert
Everything to the right will move right
Observe Blocks that overlaps with the playhead position, will NOT move!

Left-ways
You can do the same in opposite direction, for everything. This need more care, because if you move blocks to much, they will overlap, and that can be a drag!
Hold Sh + press Delete
Everything to the right will move left

Here are all lmms shortcuts listed:
