You can install multple modules in one go in dnn 4 as well. Just define it all in one dnn file (manifest). You can included multiple <module> elements for each module you want to register during installation

ah my wrong. yes, if you use multiple folder elements with each folder element having its own module definition.

Mind you: the name element of every folder node can be the same. the file would look something like this:

<?xml version="1.0" encoding="utf-8" ?>
<dotnetnuke version="3.0" type="Module">
    <folders>
        <folder>
            <name>[ModuleName]</name>
            <friendlyname>[FriendlyName]</friendlyname>
            <foldername>[FolderName]</foldername>
            <modulename>[ModuleName]</modulename>
            <description></description>
            <version>01.00.00</version>
            <resourcefile>resources.zip</resourcefile>
            <modules>
                <module>
                    <friendlyname>[FriendlyName]</friendlyname>
                    <cachetime>[defaultCacheTime]</cachetime>
                    <controls>
                        <control>
                            <title>[ControlTitle]</title>
                            <src>[ControlSource]</src>
