tcgplayer mass entry export to set and collection

Can we get a button added to the sets and collection pages to export a csv of tcgplayer mass entry?
The URI easily gets to long resulting in 414 error and there is no apparent way to get the mass entry information for the cards otherwise.

Would be nice to have a quick "create a playset of all card ids" or subset minus what is in your collection, for people new to the game that are looking to get a playset of sets from before their time in the game.

Hello! 

When you say an export of a mass entry, do you mean a list containing cards, IDs and TCGplayer purchase urls or something?

Apologies on the delayed reply, never saw notification.

(these are not the same entries, I just grabbed them as examples)

I mean the resulting codes (where are these sourced from?)
```
1-653396
1-653399
1-656293
```
or the human readable form:
```

1 Perorimon [BT-23] BT23-039 C
1 WereGarurumon [BT-23] BT23-056 C
1 BanchoLeomon [BT-23] BT23-036 U

```

When you are in Collection > Tools > More > TCGplayer Cart

this sends you to the mass entry with that string of numbers form in the url, but url has a limit of how long it can be and still be accepted. If you're trying to get a bunch of cards (starting a playset of stuff for instance) then you easily surpass that limit.

Hello again! Thanks for bringing this to my attention.

I completely forgot that this was an issue I had fixed years ago on YGOPRODeck and it's now resurfaced on these sites. TCGplayer actually have a proper Mass Entry API to be uses when the generated URL gets too long and causes 414 errors. 

I've now implemented this here and all areas that used Mass Entry (decks, cubes, sets, collection, etc) will use this new system and will no longer 414 when doing a Mass Entry call.

Thanks!

Thanks a ton @Genesis!

I did hit one that was an error just now id that it placed in mass entry was: `280275`
How do I tell what card that is to manually do it?
